Abstract:
Mycobacterial spindle cell pseudotumour (MSCP) has been reported in various sites, including skin, lymph nodes, bone marrow, lung and spleen. Cutaneous lesions are extremely rare and the differential diagnoses include various spindle cell lesions. Literature review shows that this lesion has preponderance for upper limb involvement and occurs largely in immunosuppressed individuals. We report a case of MSCP of the skin due to atypical mycobacterium and discuss the risk of misdiagnosis as a sarcoma.
